You've just seen simulations
of geologic structures formed by different stresses
under different conditions. Now, you'll examine
structures to infer the conditions and the type of stress
that was applied. Keep in mind that structures in the
real world are more complex than the models you just
saw. Structures may show evidence of more than one type
of deformation.

! Click each image to see a larger version. Examine
the photograph and try to identify the geologic structure.
To see an outline of the structure, move your cursor
over the image.

Note:
All the structures shown here show some brittle deformationthat
which broke the rock in order to expose the structure.
Focus on the highlighted structures in each photograph
for your answers.

3. Identify the type of structure, type
of deformation, and stress direction for each image.
